ABSTRACT:
A method, system, and computer program product for detecting a tailgate event between two vehicles moving in a forward motion is provided. The two vehicles include a first and second vehicle, one of the two vehicles being an offending vehicle and the other of the two vehicles being an affected vehicle. The method includes determining a distance between the two vehicles. The first vehicle is ahead of the second vehicle. The method also includes calculating a safe distance range between the two vehicles based upon one or more of speed, weight, and safe braking range values of at least one of the two vehicles. The method further includes comparing the distance and the safe distance range and activating a recording device on the affected vehicle if the distance is less than the safe distance range indicating an unacceptable range value, the offending vehicle being responsible for causing the unacceptable range value.
